Phytonadione

Phytonadione is indicated for the treatment of adults with the following coagulation disorders which are due to faulty formation of factors II, VII, IX and X when caused by vitamin K deficiency or interference with vitamin K activity. anticoagulant-induced hypoprothrombinemia caused by coumarin or indanedione derivatives; hypoprothrombinemia secondary to antibacterial therapy; hypoprothrombinemia secondary to factors limiting absorption or synthesis of vitamin K, e.g., obstructive jaundice, biliary fistula, sprue, ulcerative colitis, celiac disease, intestinal resection, cystic fibrosis of the pancrease, and regional enteritis; Other drug-induced hypoprothrombinemia where it is definitely shown that the result is due to interference with vitamin K metabolism, e.g., salicylates.

Phytonadione is a vitamin K replacement indicated for the treatment of adults with the following coagulation disorders which are due to faulty formation of factors II, VII, IX and X when caused by vitamin K deficiency or interference with vitamin K activity: Anticoagulant-induced prothrombin deficiency caused by coumarin or indanedione derivatives; ( 1 ) Hypoprothrombinemia secondary to antibacterial therapy; ( 1 ) Hypoprothrombinemia secondary to factors limiting absorption or synthesis of vitamin K, e.g., obstructive jaundice, biliary fistula, sprue, ulcerative colitis, celiac disease, intestinal resection, cystic fibrosis of the pancreas, and regional enteritis; ( 1 ) Other drug-induced hypoprothrombinemia where it is definitively shown that the result is due to interference with vitamin K metabolism, e.g., salicylates.

Phytonadione tablets are contraindicated in patients with a history of a hypersensitivity reaction to phytonadione or inactive ingredients [see Description ( 11 )] . Hypersensitivity to any component of this medication. ( 4 )

Anticoagulants Phytonadione may induce temporary resistance to prothrombin-depressing anticoagulants, especially when larger doses of phytonadione are used. Should this occur, higher doses of anticoagulant therapy may be needed when resuming anticoagulant therapy, or a change in therapy to a different class of anticoagulant may be necessary (i.e., heparin sodium). Phytonadione does not affect the anticoagulant action of heparin.

Anticoagulants: May induce temporary resistance to prothrombin-depressing anticoagulants. ( 7 )
